Letters Patfmt No. 88,584, dated Apr/il 6, 1869.

IMPROVED BEER-COOLER.

The Schedule referred to in these Letters Patent and making part: of the same.

To all whom it may concern.:

Be it known that we, HERMAN PIETSCH and Monrrz WALTER, of the city and county of Milwaukee, and

. State of Wisconsin, have invented a new and useful vthe accompanying drawing, forming part of this specification, in which- Y Figure 1 isa side view of our invention;

Figure 2, a vertical section; and

Figure 3 is a view of the top.

Similar letters of reference in each of the figures indicale corresponding parts.

The object of our invention is to produce a superior beer-cooler.

A is the'main cylinder of the cooler, made withan outer and an inner corrugated surface.

B is a pan, made double, with 'a circular opening in its centre, with a raised edge around it. Over this pan stands the cylinder A. i

C is a dripping-reservoir, setting on inder A.

b l) is a pan sitting above reservoir C, to receive the eer.

Eare spouts to conduct the beer from pan D to the reservoir C. Y

F, sponges over the ends of spouts E, to filter the beer through, and to keep back hops, dust, Sac.

G, inlet-pipe, for cold water.

H, outlet-pipe, for the water.

I, a dividing ridge on reservoir C, to divide the beer, there being two sets of holes, one on the outside and one on 'the inside, so that the beer will be divided, onehalf on the outside and one-half on the inside of cylinder A.

K, passage-pipes from pan B, and on which stands cylinder A, for the cold water to pass from the pan B to the cylinder A.

top of the cyl- L, feet of the cooler.

M, outlet-pipe for the beer to pass from pan B.

N, holes for the beer to pass through reservoir C, and down over cylinder A.

Operation. There is a tub, or cask of Water, and is connected to through the cooler, and out at pipe H.

The beer islet into pan D, passes through the Sponges into the pipes E, and is emptied into the dripping-reservoir C, and, through the holes N, on to the cylinder A, one-half on to the outside and one-half on to'the linside, it being distributed by the divider I, and runs down over the cylinder A in a thinfihn, and drops into the pan B, and out through the outlet M.

The beer strikes the upper, or top part of cylinder A, hot; it grows cooler and cooler as it passes down, till it strikes the cold pau B, and is made perfectly cool, and passes off through pipe M.

The water, if a tub, or cask is used, grows warm at or on top, and grows colder as the beer trickles down. If a pipe is attached to pipe G, and water is forced through land out of pipe H, the coldest water'is in the pan Vat the bottom, and the beer will be cooled gradually, till it will be perfectly cool when it leaves the pan by the outlet M.

We do not claim a beer-cooler made 'by combining vertical plates, as described in the patent of George B. Farrell, July 16, 1861.

What we claim as our invention, and desire to secure by Lett-ers Patent, is-

Pan D, with iiltering-sponges F and spouts E, all in combination, substantially as described.
